RENDERING AND DRYIANG APPARATUS.

SPECIIJIOATION forming part of Letters Patent No. 700,033, dated May 13, 1902.

n Application iiled June 311901( Serial No` 62,843. (No model To all whom t may concerncity, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Apparatuses for Separating Liquid from Solid Substances, Filtering the Same, and Drying theV Residue, of which the following is aspecification, reference being had to the accompanying drawings, which form a part thereof.

My invention will be described with particular reference to the apparatus shown in the accompanying drawings, which apparatus embodies one form of my invention.

In the drawings, Figure lis a central vertical section of the apparatus.- Fig. 2 is a plan View of the swinging bottom orhead; and Fig.

3 is aplan View on a reduced scale,showing the pipes and the-manhole.

In the drawings, a indicates the casing of the apparatus, which casing'is apertured at the top :for the passage of ahollow shaft b and pipes o cl. The casing is provided at the bottom with a cross-bar e, suitably supported by brackets f. The shaftb is set in a socket g,car ried by the cross-bar e. The hollow shaft l) passes through a suitable stufling-box h and is provided with a bevel-gear 7l, which meshes with a suitable bevel-gearj, carried upon the shaft 7c', mounted on the bracket Z on the casing a. Suitable hollow arms project laterally from the shaft b and are in open communication' therewith, so that they may receive steam or gases therefrom. ended, so as to deliver steam or gases into the interior of the casin g. The hollow arms fm are provided with wings, as o, preferably accom-1 plishing a quarter-turn around the said hol-l low arms. Bolted or otherwise suitably secured to the bottom of the casing' is a ring p,

having one member q of ahinge integral there# with.

r isa suitable head or bottom, shown in the present instance as dished and provided at the center with an outlet-conduit s, throughV which the liquid products may-be run oftV as soon as they are melted. Socketed in thel head n or bottom is a suitablefiltering-screen' t, covered by a body of ltering material. Swing# ing fastening-bolts u or other usual fasten- The hollow arms are open-A ings are employed to hold the swinging head Be it known that l, JOSEPH GLATZ, a citizen'V of the United States, residing at New York firmly against the ring p.

The apparatus may be used in the follow- .ing manner: yThe vessel is lled or'nearly viilled with organic substances containing oil `or fatty matters. vthedrawingsis especial-lyadaptedforusewith fish or garbage. The apparatusisthen closed The apparatus show-n in by closing the manhole, and the'hollow shaftb lis rotated by power and steam introducedinto ythe massthrough the said hollow shaft and the hollow arms m. The stirring and treatment with steamhave.. the effect of melting out the oils, fats, and greases contained in the substance or substances treated, and these oils,

fats, drie. percolate through the mass and the filtering material along with the hot waterof condensation,are thereby iltered,and at once run off through the pipe or passages, so that they will not remain in the apparatus long enough to darken them in color. When the fats, oils, the., have been thoroughly melted out of the mass, the steam is shut o and heated air at suitable temperature is introduced through the shaft b or pipe c, or both. The pipes c and d are merely auxiliary, being used'in addition to the pipe b or alone, as the necessities may require.

In order to'bring about a rapid drying, the

'hot air may be introduced through the hollow shaft and arms. The hot air passing through the mass thoroughly dries the mass, and when the mass is thoroughly dried the air is cut off and the swinging head r swung down, allowing the dried mass to bel discharged into suitable vessels. This may be further treated to con-vert it into a valuable fertilizer.

' lHaving described my invention, what I claim, and desire to secure by Letters Patent,

1. .In a combined rendering and drying apparatus the combination of a casing, a rotary hollow shaft contained withinlthe said casing, hollow arms carried by the said shaft delivering fluid to the interiorof said casing, meansfor rotating the said shaft anda removable head and screen and an outlet for duid, which may be rendered out, the said outlet being adapted to remain constantly IOO open during the rendering and drying operations.

2. In an apparatus adapted for rendering or drying the combination of a casing, rotary means for introducing and distributing heated uid into contact with the material to be treated, a sieve at or near the bottom of said casing, a run-off duct or passage receiving melted fats, rbc., and means for removably securing the sieve or screen in the casing.

3. In an apparatus adapted for rendering or drying the combination of a casing, a hollow shaft, hollow arms carried on the said shaft and communicating therewith and delivering fiuid to the interior of said casing, and stirring-blades carried by the said arms.

4. In an apparatus adapted for rendering or drying the combination of a casing, a rotary means for delivering fluid to the interior of said easing, and into contact with kthe material to be treated, and a removable head r and a screen t.

5. In an apparatus adapted for rendering or drying the combination of a suitable casing, a rotary combined stirringr and uid-de livering apparatus contained therein, the said casing being entirely unobstructed except for the said rotary apparatus, a suitable sieve or screen and means for movably supporting the sieve or screen whereby the charge may be removed from the vessels.

G. In an apparatus adapted for rendering or drying, the combination ofa casing, a hollow shaft with means for revolving the said hollow shaft, laterally-projecting Huid-conducting means carried by the said shaft, adapted to deliver fluid to the interior of said casing at points remote from the said shaft, the said laterally-projecting fluid-conducting means carrying means for effecting a stirring action on the mass.

7. In an apparatus adapted for rendering or drying, the combination of a casing, a hollow rotary fluid-distributing device, adapted to distribute ii-u'id into the said casing at the points remote from the center of rotation ot' the said duid-distributing device,a liquidoutlet and a sieve contained within the casing whereby iiuid may be introduced into the said casing at places throughout the mass contained in said casing whereby a pressure may be brought to bear upon the said mass at Widely-different points in order to force moisture out of said mass through the {iniddelivery orifice.

In testimony whereof I have signedv my name to this specification, in the presence of two subscribing witnesses, this 28th day of May, 1901.
